The framers of the U.S. Constitution decided against choosing the president by popular vote primarily due to concerns about direct democracy and the potential for mob rule. They feared that a purely popular election could lead to the election of demagogues who might manipulate public opinion. Additionally, the framers aimed to balance power among different states, so they established the Electoral College as a compromise that would allow for both popular input and a more measured selection process that considered state interests. This system was intended to ensure a more stable and informed choice for the presidency.
The Framers opposed choosing a President by popular vote because they felt that such a process would lead to "tumult and disorder." The idea of electing the head of state in any way was itself radical-- virtually all the countries of the world were ruled by people who inherited their position. Britain, from where most of the framers came, had a class system. There were lords or gentlemen who ruled , were educated and owned most of the land, and there were the common people who served the gentlemen.They felt that the country was too large for voters to learn about the candidates.
The framers wanted a presidency that could withstand intense popular pressure. It set out to accomplish this by having the president elected via the electoral college.

The constitution calls for the President to elected by electors from the states. It allows the state legislatures to decide how to choose its electors. Probably most of the framers expected the legislatures to elect the electors rather than holding a popular election to choose them.
The Framers hoped that the individuals chosen as presidential electors would be wise, informed, and independent thinkers who could make decisions in the best interest of the nation. They envisioned electors as a safeguard against the potential pitfalls of direct democracy, believing that these electors would possess the knowledge and judgment necessary to select a qualified president. This mechanism was intended to ensure that the selection of the president was deliberate and not merely a reflection of popular sentiment.
They wanted the President to be elected by the people of the United States. In a compromise (Remember, the Constitution is a bundle of compromises), they Founding Fathers decided to have an "Electoral College," a group of common civilians who's sole purpose for being elected is to go and elect the President. Of course, in this day and age, with technology making a popular vote of the President much more practical, many people advocate the abolishment of the Electoral College. They argue that the popular vote should elect the President, rather than the people who elect the President.
It allows for faithless electors, or electors who do not vote according to the wishes of their states.

The three methods of presidential election discussed by the framers of the Constitution include using electoral college, simply selecting the president, and electing directly. As of 2014, the president is elected using the electoral college.
The electoral college elects the president, not the direct popular vote. There is a reason for this, but Gore supporters were disappointed when their man was not elected president after carrying the popular vote.
At the Constitutional Convention, one of the big "rifts" was between the big and small states. Well, if it were up to popular vote, states like New York, Virginia, and Pennsylvania would hold all the influence because they held all the people -- today if we didn't have the electoral college people wouldn't bother campaigning in Vermont or Wyoming or Mississippi because those states don't have too many people (no offense if you live in those states.) So the popular vote was nicked because small states wanted equal say.
